Project Details

Description

The works are required to maintain the safety and integrity of the A77 carriageway at Smyrton, South Ayrshire. This section of carriageway is currently exhibiting various areas of cracking, crazing and potholes, as well as wear and tear of road markings, missing road studs, channels and edgings.

The scheme will be split into two phases (Phase 1 & Phase 2) due to its length.

Works will involve carriageway resurfacing utilising TS2010 surface course to varying depths dependent on condition, ranging from 40mm to 100mm across the length of the scheme.

The proposed construction activities for resurfacing will involve the following:

  • Milling of existing bituminous material by road planer;
  • Hand-held jackhammer and compressor for breaking up surfaces not accessible by planer;
  • Loader/excavator used to collect and move excess material;
  • Base/binder material laid and compressed (where required);
  • New bituminous material laid by a paver;
  • Material compacted using a heavy roller;
  • Mechanical sweeper to collect loose material;
  • Heavy Goods Vehicle (HGV) for removal and replacement of material; and
  • Road markings replaced using an extrusion tool.

Materials required for works are:

  • TS2010 surface course;
  • AC32 base;
  • AC20 binder;
  • Bitumen;
  • Road paint; and
  • Road studs.

The total area of works is approximately 24,000m2 (2.4ha) across both sides of the single lane carriageway.

The construction is programmed to be undertaken and completed within the 2025-2026 financial year, proposed for February 2026. A contraflow system will be in place 24/7 with works undertaken during day and nighttime working hours for approximately 10 days each phase.

Location

The works are located on the A77 carriageway, South Ayrshire just south of Ballantrae. The scheme is split into Phase 1 and 2. The National Grid References (NGR) for the works locations are detailed below and illustrated in Figure 1:
